IMPROVEMENT IN VARIETY-MOULDIN G- MACHINE.

The Schedule referred to in these Letters Patent andV making part of thesame To all whom it may concern Be it known that I, NICHOLAS JENKINS, ofthe city and county of New York, State of New York, have inventedcertain new and useful Improvements in Machines for Variety-Moulding infood Vorking; and I do hereby decla-re that thc following is a full andexact description thereof.

My invention relates to the table or part which sus- .tains the wood tobe moulded, and to certain devices connected therewith, in their severalrelations to the cutting-arbor or arbors, and to each other, in theproduction of such light panelling or moulding as does not require theleverage `due to the use of the moving tables.

I will first describe what I consider the best means of carrying out myinvention, and will afterwards designate the points which I believe tobe new therein.

The accompanying drawings form a partof this specification.

v Figure l is a front view, Figure 2 is aplan view, Figure 3 is a sideview, and Figure 4 is a vertical section scale.

of a part on a larger ing my table in position therein. A part oftheframing is broken away to better show the situation of the table.

Similar letters of .reference indicate like parts in all the figures.Tint-s are used merely to distinguish parts, and do not imply material.The material of the whole should be iron or steel.

The general construction and arrangement of the other parts of themachine may be substantially that described in niy'patent dated August6, 1867. There are, however, some important peculiarities in the bestt'orm of the machine as represented, and I will briey explain some ofthem. They are only important so far as they relate to the movin r tableupon which my fixed table is partly supported, and tothe cutter-arborswhich treat the wood.

A is a fixed frame.

A1 indicates upright portions thereon, to support the working-parts.-

vA3 is a broad cross-head, capable of being moved vertically on thefront of the frame-work, guided by the slides A2, and operated by thescrews A4, which are adjustable by the aid of the transverse shaft A5and the gear-wheels connecting the parts, as represented. As the shaftA5 is turned, the cross-head Aa is caused to rise or sink within widelimits.

B is a cutter-arbor, mounted vertically in bearings carried in thecross-head A3, before described.

I propose generally to use two of these arbors, running in oppositedirections, so asto cut right and left,

Figure 5 is a side view of the entire machine, showas preferred, butthis is not absolutely necessary, and I will describe them as one. It isrotated by a belt from a corresponding pulley on a back shaft, D, as

represented, and the bearing for the belt on the cutterarbor, or ratherou the long drum or pulley, which is fitted thereon, is sufficientlylong to allow the motion to be properly communicated in all positions.

The cutter which produces the mouldings, or the panel-work, may beeither plain or variously ornamental, and the operation of moulding orpanelling is effected in my machine vas in my former one, by loweringthe cutter so as to enter the wood to a proper extent, and then movingthe Wood horizontally in various directions, so that the cutter shallexcavate a groove either straight or variously curved. The arbor may beraised and lowered to a great extent with facility, and adj usted at anylevel desired.

E is the movable carriage. 'W'hen used to carry the stuff in heavy workthere are frames bolted thereon, adapted to receive the boards or planksto bepanelled or moulded betweensuch frames and movable clamping-pieces.One of these vframes is partially visible near the back end.

This carriage E is moved transversely from right to left, and from leftto right on the movable under table or carriage F at will. Theundertable Fis traversed backward'and forward longitudinally at will,carrying the other with it.

The proper traversing motion is given to the table F by operating acrank-shaft, F2, and in giving the lateral motion to the upper table E,the crank E* is used.

The above moving-carriages are necessary for the production of heavywork, but for -all kinds of light work I can move the wood by the directapplication ofthe hand, movig it longitudinally and laterally, asrequired, upon a xed table, but it is necessary to enlployvery-ettieient and delicately-adjustable guiding means. This table andguides form my present invention. f

V is my portable or removable table.

It has short supports or legs Vl V, adapted to rest on thetransversely-sliding table or carriage E, before described, and longersupports or legs VZ, extending down into holes in the frame-work A, asrepresented, and adapted to be secured there firmly by means of thecollars V3 and nuts V4. Y

I use this table iu variety-moulding, and I fix the wood to be cut uponthe pattern which is to guide it. The table V remains immovable duringthe whole operation, and I move the pattern and the Wood thereon bysliding it about on the table V, pressing it meanwhile against a pin, W,which is xed in the table V, exactly in line with the cutter-arbor,audits cutterprevolving rapidly above, as before described.

The pin W has its upper portion smooth and cylin drical, and so muchsmaller than the threaded portion below it that it can be sunk into thetable 'to any depth desired, and it is peculiarly adjustable. It may beadjusted so as to protrude upward more or less above the surface of thetable V, by simply seizing it with pipetongs or any analogousinstrument, and screwing it up or down.

The nut NV o n the lower end being setup afterward, confines it veryfirmly.

In order to change the pin W, substituting a larger or smaller atpleasure, I remove the socket X, and insert another which has acorrespondingly larger or smaller hole.

Itwill be understood that I have several sockets X, and several pins W,of different sizes, adapted thereto, the exterior' of all the socketsbeing alike.

The nut W is of such size as -to extend over or beyond the socket, andto bear on the fixed boss V5, which is a part of the table V, and thusto bind and afford a firm support, and confining-means both for thesocket and pin. The tightening of the nut NV' will tighten both thesocket and the contained pin. I can, if preferred,obtain nearly the sameeffect by using a smaller nut and au intermediate washer of suitablesize. Vith either arrangement, properly-tightened, the friction of' thethreads of the pin Vf, and also of the large sockets X, will confinethem with absolute rmness.

There may be a head on the lower end ,of each of the pins W, in which case each will, of course, be inserted into its respective socket X frombelow, and it can be adj usted by applying a suitable wrench or key tothe head, instead of seizing the small part of the pin.

Some of the advantages due to certain features of my invention may beseparately enumerated, as follows:

First, by reason of' the fact that my removable table V is adapted toform a level surface, when applied as represented, resting atY 'carriageE, and firmly bolted at the other end upon the frame-work A, I am able,with thesame machine,

to secure firmness of support due to an absolutely fixed table, forproducing light work, without forfeiting the advantages of the movablecarriage, for eecting heavy cutting.

one end upon the traversing ,Second, by reason of the fact that my pinsare adjustable vertically by means of the screw-threads thereon, and arefixed firmly in either position by the nut W onthe under side, asrepresented, I am able to secure the advantages due to a high pin orguide in working ordinary thick stuff, and thus to reduce the risk ofriding over it, `and can, by a ready adjustment, adapt the part-s to thetreating of very thin stuff. y

Third, by reason of' the fact that the sockets X, in which theadjustable pins W are set, may be changed, as represented, I am able toemploy pins of larger or smaller diameter at will, and thus employ pinscorre sponding as exactly to the diameter of .the cutter as may berequired, without sacrificing the capacity of adjustment of the pinsvertically. Any difference in diameter between the guiding-pin W and thecutters 1 z causes the panel-work to differ in design from the patterns,and therebyintroduces confusionwhich this provision avoids,

Having now fully described my invention,

What I claim as new, and desire to secure by Letters Patent is asfollows:

1. The removable table V, and pin set therein, arranged to serverelatively to the carriage E, framework A, and cutting-arbonB, andhaving the plain legs Vl and the screw legs V2, for fixing the table inan invariable position relatively to the said arbor, all as herein setforth.

2. Incombination, the cutter b, raised and lowered as specified, thestationary surface V, and the adjustable pin W, having its cylindricalpart smaller V'than the threaded part, stantially as and for thepurposes herein set forth.

3. The changeable threaded sockets X, in combination with the changeablepins W, adjustable vertically, as represented, and with the table V androtating cutter, adapted to move vertically, all substantially as andfor the purposes herein set forth.

' In testimony whereof, I have hereunto set my name in presence of twosubscribing witnesses.
